Detailed explanation-1: -Actions that occur without the involvement of the brain are called involuntary actions, while planned actions from the brain, like throwing a ball or strumming a guitar, are called voluntary actions.

Detailed explanation-2: -All the reflex actions which involve brain are called cerebral reflexes. They occur in the organs present in the head because these organs are directly connected to the brain.

Detailed explanation-3: -A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.
